An installable plug-in for AutoCAD

Add an AI assistant directly inside AutoCAD

PrismCAD is a plug-in—not a separate CAD program. You install it on a Windows computer running AutoCAD 2025 or 2026, then use PrismCAD commands from inside AutoCAD. Your DWG and DXF drawing files remain on that workstation.

PrismCAD reads the current AutoCAD selection, translates plain-language instructions into explicit CAD operations, and shows the planned commands before anything runs.

  • Works with the active drawing contextSee the selected object count, layers, entity types, project and indexing status without leaving AutoCAD.
  • Turns intent into reviewable commandsA request such as “rotate the selection 85 and move south 76” becomes named operations with visible parameters.
  • Keeps the user in controlPrismCAD explains what it matched and waits for approval before executing the command plan.
  • Returns traceable resultsSuccessful runs display an execution ID for diagnostic review while the drawing remains on the workstation.

First-use walkthrough

From installation to an approved AutoCAD command plan

The free beta follows a clear five-step path. Install the plug-in, open AutoCAD, activate the signed license, describe the drawing task, then review and approve the proposed commands.

The problem

CAD assistance should not require surrendering the drawing

Proprietary plans, layouts, and drawing geometry can be too sensitive to send to a hosted assistant. PrismCAD is designed around a local drawing boundary and a fail-closed license path.

Keep drawing bytes local

PrismCAD does not upload DWG or DXF files or Autodesk passwords.

Verify the command path

The plugin accepts an Insight ITS Ed25519-signed beta license, not an arbitrary emailed string.

Know what telemetry means

The free beta states its diagnostic-log exchange before a license is issued.

How installation and activation work

Install the plug-in, then activate it inside AutoCAD

Download

Get the official PrismCAD plug-in package from this website or the public GitHub release page when downloads become available.

Install into AutoCAD

Install the plug-in on Windows for AutoCAD 2025 or 2026. PrismCAD then appears as commands you run inside AutoCAD.

Accept and activate

Accept agreement prismcad-beta-telemetry-1, run PRISMCADLICENSE in AutoCAD, and paste the issued PCAD-BETA key.

Verify

Run PRISMCADHEALTH inside AutoCAD and confirm license: Licensed.

Evidence boundaries

Exactly what stays local—and what the free beta sends

Never sent as part of this contract

DWG/DXF drawing bytes, Autodesk passwords, and customer LLM private keys are not uploaded.

Consented beta diagnostic log

When its content changes, PrismCAD may upload the sanitized local JSONL agent diagnostic log over HTTPS at most once per UTC day. It can contain prompts, operation names, entity handles, routing nodes, timestamps, run IDs, and event payloads.

Read the full privacy and diagnostic-log notice. The free beta will not run without a valid license and agreement.
